问题描述：
1.My dad promised to buy a new car and _____ it.
为什么选B 这个?A.that he would let me drive B.to let me drive
C.that I would ask him to drive D.promised to let me drive
答
B
因为从and可以看出，前后句式要一样，所以A、C可排除，而D有重复，所以也不行，故只有B最好！
答
A： and后面跟that不行的，直接不要and，就可以
C： 也一样
D：表述罗嗦，重复，前面已经有promised
第二个，就是D的不重复不罗嗦版本。其实就是promise to buy and promise to let me drive
答
因有and,要连接两个并列的结构,前面用了不定式to buy a new car ,故后面也用不定式 to let me drive .
